You are a fancy rat breeder investigating different characters in fancy rats. You have two true breeding populations of rats. One population's fur color is all brown. The other population;'s fur color is all black. You breed members of the brown population to members of the black population to get an F1 generation. The F1 generation grows up, you find they are all brown. You breed members of the F1 generation to other members of the F1 generation to get an F2 generation. When the F2 generation grows up, ~75% if them are brown, and ~25% of them are black. Statistically significant numbers of rat pups were produced in each cross. 1.Give the phenotype ratio of the F1 generation 2.Give the genotype ratio of the F1 generation. Give the individual genotype(s) 3. Give the phenotype ratio of the F2 generation. 4. Give the genotype ratio of the F2 generation. Give the individual genotype(s)
